| Sumario: | Part of a special issue on visual attention. A study was conducted to analyze the effects of cue probability on the allocation of visual attention. Data were collected from three male observers who observed a cue to indicate the likely location of a target out of four possible target locations. Findings indicated that the observers had higher target discrimination accuracy at highly probable locations than at less probable locations and that these differences were maintained across all cue-target onset intervals. Subjects seemed to be allocating attention as a function of cue probability, with a consistent pattern throughout the time course of the development of attention. It is concluded that the consistent pattern across stimulus onset asynchronies indicates that the effects of time after cue and the effects of probability may depend on independent processes. |
